Breaking the Sound Barrier (1952)
The Sound Barrier is a British 1952 film directed by David Lean. It is a fictional story about attempts by aircraft designers and test pilots to break the sound barrier. In the U.S. it was retitled Breaking the Sound Barrier. David Lean's third and final film with his wife Ann Todd was also his first for Alexander Korda's London Films, following the break-up of Cineguild. The Sound Barrier was a great box-office success, but it is now rarely seen and has become one of the least-known of Lean's films. It is also Lean's only venture into this type of genre.
